Epsilon, Altegrity and Acxiom– these for-profit intel behemoths are involved in everything from debt collection…

As big as Infogroup is, there are dozens of other for-profit intelligence businesses that are even bigger: massive multi-national intel conglomerates with revenues in the billions of dollars. Some of them, like Lexis-Nexis and Experian, are well known, but mostly these are outfits that few Americans have heard of, with names like Epsilon, Altegrity and Acxiom.

These for-profit intel behemoths are involved in everything from debt collection to credit reports to consumer tracking to healthcare analysis, and provide all manner of tailored services to government and law enforcement around the world. For instance, Acxiom has done business with most major corporations, and boasts of intel on “500 million active consumers worldwide, with about 1,500 data points per person. That includes a majority of adults in the United States,” according to the New York Times.
